Summary — Distance Lost + Projected Potential

19'10" happened with good board speed. The next jump is an inches story — 12.5 inches sitting in mechanics, not fitness.

What Changes The Jump

Alexis-specific

Landing finish: hips through

Lands slightly sitting back

Gain

+6"

Steps 13-14: stop reaching

Drift starts searching for board

Gain

+2-4"

Takeoff: stiffer strike

Contact time reduces launch carry

Speed (mph) by step — measured vs. target

Alexis read: Speed builds well to step 12. Steps 13-14 she hunts the board — cadence drops, drift begins, contact time extends.

3-Step Plan

Alexis plan

1) Landing finish (today)

Hips through feet, no sit-back

Gain

+6"

2) Match steps 13-14 (next session)

Drift disappears, board window stabilizes

Gain

+2-4"

3) Stiffer takeoff (once stable)

Shorter contact boosts vertical velocity

Gain

+2-3"

Bottom Line

Summary

Alexis is fast enough for 21 feet. The 12.5 inches break down cleanly: landing finish is +6" (fastest fix today), step stability is +2-4" (next session), takeoff stiffness is +2-3" (once approach stabilizes). None require more training volume — just better mechanical execution of what she already has.
